Improved handling of custom G-code blocks: Slic3r will try to extract
the target extruder and bed temperatures from the custom G-code blocks.
Removed Perl Flow::new_from_spacing bindings.
Some Fill C++11 beautification.
Fix of a support_material_1st_layer_flow, brim_flow and skirt_flow logic to use the extrusion_width if both first_layer_extrusion_width and support_material_extrusion_width are undefined.
Documented the extrusion width logic in the config tooltips, including the default values.
The values of StaticPrintConfig derived objects were searched by a name
walking through a huge chained if.
Now they are being mapped with a std::map.
Also initialization of StaticPrintConfig classes from their ConfigOptionDef
defaults is done by maintaining a single global definition of each
StaticPrintConfig derived class, and a new instance is initialized
from this static copy.
Also the ConfigOption instances are casted using static_cast
wherever possible, and their types are verified by a virtual type() method.
This approach avoids insiginificant performance penalty of a dynamic_cast.
Also the compare and clone methods were added to ConfigOption,
and the cloning & compare work on binary values, not by serialization.

Change of the PlaceholderParser:
All vector configuration values stored into the PlaceholderParser
are expected to be addressed by the extruder ID, therefore
if a vector configuration value is addressed without an index,
a current extruder ID is used.
Also a small fix of fan handling: The fan speed is set to zero
at the start of the G-code if the cooling for the initial extruder
is disabled.

The constraint for the "Wipe Tower" checkbox has been raised, so
one will get this error message only if the printer settings has more
than one extruder configured, as the wipe tower does not get generated
for a single extruder print.

Implemented a correct layer height preview for the wipe tower layers,
if the wipe tower layer height is not constant due to the application
of raft.
Removed GCode.pm
Removed the Perl bindigns for AvoidCrossingPerimeters, OozePrevention, SpiralVase, Wipe
Changed the std::set of extruder IDs to vector of IDs.
Removed some MSVC compiler warnings, removed obnoxious compiler warnings when compiling the Perl bindings.
Removed the questionable Pressure Advance feature. It is better to use the Pressure Advance implemented into a firmware.
Added a C++ implementation of GCodeReader and SpiralVase, thanks to @alexrj
Added a C++ implementation of GCodeTimeEstimator, thanks to @lordofhyphens
When extruding supports, the support is interleaved with interface
if possible (when extruded with the same extruder).
Otherwise the base is extruded first.
Reset the layer height profile when changing a print profile to an incompatible one.
Reset button on the layer height bar.
Fixed an update issue on zooming by a scroll wheel.
Fixed an issue when loading an AMF file: Object names are now retained.
inside ClipperUtils are now using bit shifts instead of multiplication
by doubles, which makes the scaling precise.
Removed the scale parameter from all offset functions.
Modified the safety offset to calculate offset per polygon instead
of over all polygons at once. The old way was not safe and very slow,
sometimes this meant a kiss of death for supports for example.
